Title: Semiconductor chip temperature controller
Inventor: SUYAMA YOSHIMITSU
IPC: H01L21/66
Filed: 1978-10-20
Abstract: PURPOSE: To simplify the procedure of constantly keeping the temperature of a semiconductor chip to which electrical energy is supplied, by blowing hot winds against the chip, by detecting temperature by means of an infrared ray thermometer and by controlling a hot-wind source by using a comparator.  
     CONSTITUTION: A gas blow-off protion 4 building in a heater 3 is disposed in the oblique direction to a semiconductor chip 1 provided with electrical energy by means of a measuring system 2, and gas 8 warmed is blown against the chip 1 from the portion 4. An infrared ray thermometer 5 is beforehand mounted just above the chip 1, the surface temperatures of the chip 1 are detected and voltage levels V 1  are obtained. The levels are applied to a comparator 6, to which the reference level V 2  is previously input, and compared with the level V 2 , and output levels V 3  gained are fed back to a power controller controlling the heater 3. Consequently, the chip 1 is kept at a fixed temperature, and electrical characteristics are inspected. Thus, the constant keeping of the temperature of the chip is simplified, and the temperature is detected in a non-contact shape.

Title: Rail
Inventor: SATO MITSUHIRO
IPC: B65G43/00
Filed: 1993-05-31
Abstract: PURPOSE:To promote the facilitation of setting a traveling carriage, etc., and vice versa by attaching a guide rail part to the cross direction end of a ceiling rail part rotatably outwards in the horizontal direction. CONSTITUTION:One short carriage detachable rail 3 being longer than the length of a carriage 1 in order for setting a traveling carriage 1 and vice versa is installed in a main line rail 2 or required numbers of it are installed at intervals otherwise. In addition, when the traveling carriage 1 is removed from a state of being attached now, the traveling carriage 1 is pushed up, adding some flotage to it after an optional support block for drop prevention is installed in a lowermost part of the carriage 1. Next, two bolts 19 of a ceiling rail part 4 are loosened to some extent. Since each bolt 19 merely presses two guide rail parts 5 and 5 to the closing direction, if these bolts 19 are sufficiently loosened, energizing force in the closing direction by dint of a compression spring 23 is also released, whereby these guide rail parts 5, 5 are easily opened outwards in the horizontal direction with the ceiling rail 4 as the center by a hinge 17. In this state intact, when the carriage 1 is lowered downward, it is thus removable.

Title: Dry etching process
Inventor: NAKAYAMA ICHIRO
IPC: H01L21/3065
Filed: 1986-06-04
Abstract: PURPOSE:To prevent any undercut while improving the anisotropy by a method wherein, in case of etching an Si substrate, the multiple layered mask with intermediate layer comprising at least three layered mask layer formed into wider shape than the lowermost layer and the uppermost layer is used. CONSTITUTION:In case of etching a silicon substrate 4, a mask is formed into at least three layered structure using multilayered mask with an intermediate layer mask 6 formed into wider shape than the lowermost layer 5 and the uppermost layer 7. Ions entering perpendicularly into the Si substrate 4 react on the Si substrate 4 but ions entering obliquely into the Si substrate 4 are absorbed into the mask 6 of intermediate layer as recessions in a multilayer- structured mask formed into entirely recessed shape not to reach the Si substrate 4. Through these procedures, any undercut can be prevented from occuring while improving the anisotropy.

Title: Semiconductor device
Inventor: YAMANISHI YUJI
IPC: H01L29/78
Filed: 1989-05-22
Abstract: PURPOSE:To increase the breakdown strength between a source and a drain without enlarging the area of a MOSFET or without changing VT by forming a layer of N- or P-type being opposite type to a well on the opposite side to the source and drain regions of the well, and applying the voltage of the same polarity as the drain region to the layer. CONSTITUTION:In a semiconductor device wherein a source region 2 and a drain region 3 are formed in a well 1 for P-type or N-type channel, an N-type or P-type layer 4 being the opposite type to the well 1 is formed, and voltage of the same polarity as that of the drain region 3 is applied on the layer 4. Hereby, in the case that voltage is applied between the source 2 and the drain 3, before breakdown phenomenon occurs between the drain 3 and the well 1, the depletion layer A from the drain region 3 contacts with the depletion layer 3 from the P-type layer 4, so the circumferential shape of the depletion layer A on the side of drain region 3 becomes straight line shape without distortion, accordingly breakdown phenomenon becomes hard to occur, and breakdown strength can be increased.

Title: Method for measuring temperature of substrate and method for controlling temperature of substrate, and apparatus for processing substrate using the method
Inventor: MASUDA MITSUHIRO
IPC: G01J5/00
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a substrate-processing apparatus which can correctly measure a temperature of an optional area of a heated substrate. SOLUTION: The substrate-processing apparatus treats a substrate 9 supported by two projecting parts 17p and a touch-type thermometer 21 in a process including heating. In the apparatus, a first temperature Tt of a first area RA on the substrate 9 is correctly obtained by the touch thermometer 21, and second temperatures Tia-Tid of second areas Ra-Rd are obtained by noncontact-type thermometers 22a-22d. A ratio of the first temperature Tt and the second temperature Tia of the second area Ra closest to the first area RA is set as a correction coefficient K (=Tt/Tia). Each of the second temperatures Tib-Tid is multiplied by the correction coefficient K, whereby correct temperatures of the second areas Rb-Rd are obtained.  In this manner, the temperature of an optional area can be correctly measured with the use of the noncontact thermometers without being influenced by a surface state of the substrate 9, etc.

IPC: H04B10/80
Filed: 1980-09-17
Abstract: PURPOSE:To decrease power consumption the off state of the power supply of an optical transmitter at the side to be power-supply-controlled, by detecting the presence of optical signals from an optical transmitter at the power supply control side and giving instruction of on/off to the power supply in a station to be controlled. CONSTITUTION:When an optical signal is transmitted from an optical multiplex transmitter, light is converted into electricity at an optical-electric conversion circuit 6 of an optical multiplex transmitter 3 at the power supply controlled side, and a power supply circuit 12 is operated with this electric signal. Thus, in the transmitter 3, since only the circuit 6 can always be turned on, the power consumption at the off state of the power supply of the device 3 can be reduced remarkably. Since components which are always turned on are less, the device is long in life and the reliability can be increased.
